There's no doubt we live in a post-Jackass world when a ludicrous comedy like Beerfest opens with a 'Don't try this at home or you will dieâ?� warning. As tongue-in-cheek as the caveat may be, it is possible that some sloshed frat boy might try to stage his own underground drinking Olympics. (More likely, medals already have been awarded for just such an event.) This inebriated alpha-male fantasy from the Broken Lizard comedy troupe (Super Troopers) is a parody of sports films in which a team of underdogs ' in this case beer drinkers ' train relentlessly for a chance at the Big Game. As is typical, the plot is wafer-thin, convoluted and merely the skeleton on which to hang stupid beer jokes that are an affront to just about everyone, particularly women. Its most egregious trait is the inability to conjure up laughs over the course of two hours.
